CASH REGISTER.

Original application filed December 21, 1922, Serial No. 608,281. 'Divide& and this application filed November 16, 1925. Serial No. 69,401.

This invention relates to cashregisters and like machines, and more particularly to machines of the type shown and described in the application of Bernis M. Shipley, Serial No. 608,281, tiled December 21 1922,

of which this is a division.

In general.

Described in'general terms, the machine is'adapted to register a plurality of items and then print and indicate a total oi said items. The cash drawer and alarm bell, which ordinarily operate when'registering items, will, in the present embodiment, be inoperable at that time, but will operate during the time of printing and indicatin the total. b

Operating me0ham'sm.-The machine is manually operated by a handle (Fig. 2) provided with a stud 31 extending into a short tubular bearing secured to the ri hthand frame of the machine. Rigid i ith the handle 30 is a pinion 32 meshing with a gear mounted on a stud 3 1 projecting irom the frame of the machine. The o-ear 33 meshes with a gear 35 secured on the ma n driving shaft 36. The ratio of the pinion 32 and gear 35 is such that two rotations of the handle will cause one rotation of the shaft 36. i

The machine may also be operated by an electr c motor of the well known type illustrated and described in Letters Patent of the United States, No. 1,14AA18, granted to Charles F. Kettering and lVilliam A. Chryst on June 29, 1915. For a detailed description of the same, reference may be had to that patent. Only a part of the motor clutch mechanism is shown in the accompanying drawings.

A shaft 37 (Fig. 7 supported in a motor irame member 38 is rotated by the electric motor, as is fully described in the above mentioned patent. Secured to this shaft is a gear 39 which is in mesh with a gear 40 freely mounted upon the stud 41. At tached toand rotating with the gear 40 is another gear 42 which meshes with a pinion 43 pinned to the shaft 36. The gear 10 meshes with a pinion 4A- pinned to a shaft 45. Secured to the shaft 37 is a member 46 01 the motor clutch, to which is fastened a plate 1-7. This plate is normally engaged by a lever 48 fulcrumed on a stud 49. Secured to the lever 48 is an arm 50 carryin a pin 51 which normally rests on a curved edge 52 of an arm53 freely mounted on the shaft 45. The arm 53 is connected by a link 54 to a bell crank lever 55, which is secured to a shaft 56 extending across the entire machine and journaled in the frames thereof. lNhen the bell crank lever is rocked clockwise to release the machine, as will hereinafter be described, the arm 53 is rocked clockwise out of engagement with the pin 51, permitting a spring 65, attached to the arm 50, to move the lever 48 out of engagement with the plate 17. Upon the release of the lever 418 the plate 17 and its associate clutch members will move clockwise to operate the machine, as is fully described in the above mentioned Kettering and Chryst patent.

The lever 18 is restored to locking position, as shown in Fig. 7, near the end of the operation of the machine by means of an arm 66 secured to and rotating with the shaft 15. This arm engages a projection 67 on the lever 48 and causes it to move in a counter-clockwise direction to engage its lower end with the various clutch members to stop the machine, as is fully described in the Kettering and Ghryst patent previously referred to. As the lever moves in a counter-clockwise di rection, the pin 51 is elevated above the curved edge of the arm 58, permitting said arm to be returned to normal position by a counter-clockwise movement of the shaft 56 which will hereinafter be described.

Keg b0ard.- he keyboard mechanism of the present machine is the same as that shown and described in the before mentioned Shipley application, Serial No. 608,281, and reference is hereby made thereto for a full description of the same. Only a brief description of the keyboard and its cooperating mechanism will be given herein.

The keyboard comprises a plurality of banks of amount keys 68 (Fig. 1), one bank of transaction or classification keys 69 (Fig. 2), a key 70 for releasing a depressed transaction key, a starting key 71 and a total lever 72, which is for the purpose of controlling the machine for total and sub-total printing. The keys 68 of each amount bank are mounted in an individual frame 73 (Fig. 1) supported on cross rods 74 carried by the machine frame. The keys are retained in their normal outward position by compression springs not shown here.

hen a key is depressed, it cooperates with a detent 75 and is thereby retained in its depressed position, as is well known in the art. Each bank is provided with a zero stop pawl 76, pivoted to the frame of the bank and adapted to be rocked to ineffective position upon the depression of any key in the bank, and held in this position until the parts are again moved to normal.

The present machine is normally released for operation by the depression of the start ing key 71, which releases the shaft 56, as is fully described in the Shipley application previously referred to. This shaft 56has a lever 77 (Fig. 2) fastened to it outside the right-hand frame of the machine. The lever 77 carries a screw stud 78 upon which are pivoted two members 79, placed on each side of a link 80, which is slotted to move over the stud. The coiled spring surrounding the lower end of these members is compressed between shoulders on said members and an end wall of a slot 82 in the link 80. From this it can be seen that as the shaft 56 is released by the depression of the starting key 71, the spring 81 will move the shaft 56 clockwise and thereby release the motor clutch mechanism, previously described. A pin 83 mounted in the side frame controls the clockwise movement ofthe shaft 56.

The amount keys 68 (Fig. l) are locked against manipulaton after the starting key is depressed by an arm secured to the shaft 56. This arm is provided with a pin 91 extending into a slot 92 in a link 93 pivoted on a stud 94. This link is connected to a plate (not shown) which, when the shaft 56 is rocked in a counter-clockwise direction, is moved into position to lock the before mentioned keys, as is fully described in the Shipley application previously referred to.

it ear the end of the operation of the machine the parts operated by the depression of the starting key are restored to their normal position by a cam 95 (Fig. 2) formed in the gear 33. Cooperating with this cam is a roller 96 mounted on a stud carried by an arm 97 freely mounted on a stud 98 projecting from the side frame of the machine. The upper end of the arm 97 carries a pin 99 which normally engages a slot 100 fornn d in the link 80. As the gear rotates, the arm is moved first clockwise and then counter-clockwise, which causes the link 80 to move downward and return to operate the shaft 56, as is fully described in the Shipley application previously referred to.

The total lever 72 is provided for the purpose of controlling the machine in total and sub-total printing operations, during which the cash drawer and alarm both are oper ated, as will also be hereinafter described.

Di/j'erential m-ec/ia nism.-lhe differential mechanism of the machine is employed differentially to operate the dill'erent totalizers and to select them for operation, and also to set type carriers in the printing mecha nism as controlled by the various banks of keys. The differential mechanism for an amount bank of keys 68 (Fig. 1) will be briefly described.

There is a differential unit for each of the amount banks, and two extra units of higher denominations which are operated in adding operations only when a transfer to them is necessary. Each unit is supported by a pair of plates mounted upon rods 106. The rodv 107 extends through all of the differential units and acts as a stabilizer for the same.

Each differential unit is driven by a pair of cams 108 and 109 fixed on the shaft 36. These cams cooperate with rollers 110 and 111, respectively, on a lever member 112 pivoted on a stud 113 supported in one of the plates 105.

To the upper end of the lever 112 is pivoted a link 114 which is connected to a segment loose on a hub fastened in one of the plates 105. The rotation of the cams 108 and 109 causes the segment 115 to move back and forth. I

There are two differentially movable segments 116 in each unit, which are caused to move counter-clockwise with the segment 115 by a latch member 117 connected with a bell crank arm 118 which is adapted to engage with a depressed key and break the connection between the segment 115 and the segments 116 so that the segments 116 move differentially according to the key depressed. Each differential unit is connected by a link 119 to a segment 120 which meshes with a horizontal rack 121 on a car riage supporting indicator plates; The carriage shown supports two groups of indicator plates 122 and 123 adapted to indicate both to the front and rear of the machine, all of which is fully described in the Shipley application previously referred to. The lower end of the link 119 is connected to an arm 124 which is secured toa telescopic sleeve 125, operatively connected to a type bearing member used in printing the transaction upon record material. The link is positioned under control of the differential mechanism by an arm 126 pivoted on the differential unit and bifurcated at its lefthand end to engage a stud 127 carried by the link 119. The middle portion of the arm is oriven to the position shown in Fig. 1 by a roller on the lever 112 as usual.

The machine is equipped with two groups of totalizers and 136 which are operated by the differential segments 116, as described in the Shipley application previously referred to.

Oats-h drawer and beZZ;-In a machine of this type where a plurality of items are registered and a total of the same is printed and indicated, it is desirable to have the cash drawer and bell function only during totalizing operations. Therefore, when the totalizing lever 72 is in the adding position, as shown in Fig. 8, the cash drawer 138 and the bell 139 will not be operated. But, when the totalizing lever is moved either clockwise or counter-clockwise to the various total printing positions, the cash drawer and bell will be operated during the operation of the machine.

The shaft 36, whichrevolves in a clockwise direction at each operation of the machine, has secured to it an arm 140 (Fig. having a laterally projecting pm 141 moving in the plane of an arm 142 fastened to a rod 143 supported in side frames of the machine.

There is also secured to this rod another arm 144 to which is attached a spring 145 to normally hold the arm 142 in engagement with the shaft 36. \Vith the total lever 72 (Fig. 8) in the adding position, an operation of the machine will rock the rod 143 without affecting either the cash drawer or-the bell. The arm 140 actuates the arm 142 between 135 and 201 degrees of each rotation of the shaft 36. i

Movement of the total lever 72 to any of v the total-taking positions effects movement of shaft146 in a clockwise direction, and by mechanism later described causes the machine to perform a two cycle total-taking operation. This movement is effected by a. slot 147 (Fig. 8) in the total-taking lever plate 148 cooperating with a pin 149 carried by a lever 1.50 freely mounted upon a stud 151. Also'mounted on the stud 151 is an arm 152 cooperating with the lever '150to form a cam slot 153, with which a pin-154 engages. This pin is mounted in an arm 155 fastened to the shaft 146. The arm 152 is retained in its normal positionwith respect to the lever by a spring 156 attached to a pin 157 in the lever and a pin 158 in the arm 152. As the total lever is moved from the adding position, in either direction, the formed slot 147 causes the lever 150 -to move counter-clockwise, which with the..cooperation of the arm 152 moves the arm and rod 146 clockwise through their initial movement. 1

Fastened to the rod 146 (Fig. 5) is an arm to which is pivoted a link 166. The right hand end of the link has an elongated opening 167 engaging a pin 168 (Fig. 4) projecting laterally from an arm 169 fas tened to a rod 1.70. Initial movement of the rod 146 places the right-hand end of the elongated opening 167 in engagement with the pin 168. As the machine is operated the rod 17 0 is rocked counter-clockwise by a further movement of the link 166 by mechanism to be hereinafter described. The movement of thelink to theleft occurs between 221 and 301 degrees of thefirst cycle of a two cycle total-taking operation as will be described.

Secured to the rod 170 is an arm 171 having a pin 172 engaging a slot 173 formed in a sliding plate 174 which is guided inits movement by two studs 175 mounted in a drawer plunger lever 176 andextending into a slot 177 in the sliding plate.

As the arm 171 moves counter-clockwise, theplate 174 moves forward, placing a shoulder 178 in a position to be engaged by a projection 179 on the arm 144 which is secured to the rod 143. lVith the plate 174 in this forward position, the counter-clockwise movement of the rod 143 will cause the drawer plunger lever 176 to swing in alike direc tion and lift a drawer plunger 180 to release the cash drawer 138. 1

The drawer plunger is mounted in a base 181 of the frame, with a spring 182 entwined about the plunger between apin 183 and the base. A collar 184 secured to the drawer plunger, above the base, controls the lower position of the plunger. In the. upper end of the plunger is a vertical slot- 185, in which the drawer plunger lever freely operates. A horizontal pin 186 secured in they plungerengages an elongated opening 187 formed in a drawer plunger lever. The opening in the drawer plunger lever is elongated for the purpose of permitting the plunger to rise when closing the cash dra wer,'without moving the lever, and also to allow a greater movement of the lever than that required to lift the plunger.

A spring 195 attached to a pin 196 mounted in the base and to the arm 169 moves the rod 170 clockwise to return the plate 174 to normal position.

As the plunger rises it disengages from a bracket 197 fastened on the back of the cash drawer, allowing a spring 198 to move the drawer forward. As the drawer moves forward the bell crank lever 199 (Figs. 5 and 6), freely mounted upon the rod 170, moves clockwise under the action of a spring 200 until an ear 201 formed on the lever 199 engages a shoulder 202 formed on the link 166 which has been moved forward during the operation of the machine. lVith the link 166 latched in its forward position, the total lever 72 cannot be returned to the adding position. This condition makes it necessary to return the cash drawer to its normal posi tion, which moves the lever 199 counterclockwise and disengages the ear 201 from the shoulder 202 on the link 166.

The drawer plunger lever 17 6, in addition to releasing the cash drawer, operates the bell mechanism. The forward end of this lever has a formed ear 203 which normally engages a pin 204 projecting laterally from a bracket 205 secured to the base 181. Freely mounted upon a stud 206, secured in the bracket 205, is a bell hammer 207. In the normal position of the hammer, a shoulder 208 thereon engages a pin 209 projecting laterally from the bracket 205. This hammer is retained in this normal position by a spring 210 attached to a pin on the frame and to a lever 211 freely mounted on a stud 212 secured in the bell hammer. The lever 211 has a forwardly extending arm 213 normally in contact with a pin 214 on the hammer, and also an upright extending arm 215 in the plane of the car 203 on the bell hammer lever. As the bell hammer lever moves counter-clockwise. the car 203 engages the arm 215 and causes the bell hammer to move clockwise on its pivot until the ear disengages from the arm, at which time the bell hammer returns to normal position under the tension of the spring 210. A pin 216 'mounted in the arm 144 engages a projection 217 extending downwardly from the drawer plunger lever, and as the rod 143 moves clock wise this lever is returned to normal position.

As total and sub-total operations require two cycles of operation of the machine, it is important that the cash drawer and hell do not function until near the end of the second cycle of operation. Referring to Fig. 8, the lever 72, which is shown in the adding position, when moved into a total or sub-total position, controls the mechanism to prevent the restoring of the motor locking lever 48 (Fig. 7) to normal locking position until near the end of the second rotation of the shaft 36. Slidably mounted on the stud 34 (Fig. 2) is a link 225, one end of which is pivoted to a lever 226 loose on the stud 98. This lever is connected by a link 227 to an arm 228 pinned to the shaft 146. The link 225 has a stud 229 engaging a slot 230 in the link 80. The link 225 has two pins 231, one on. each side of a projection 232 of a plate 233 slidably mounted in agroove 234 in a disk 235. The link 225 also has an anti-friction roller 236 normally in engagement with a notch 237 in the disk 235. The gear 33 has a circular depression 238 (Figs. 2 and 3) in which the disk 235 is located.

From previous descriptions it will be remembered that the movement of the total lever 72, either clockwise or counter-clockwise, for a total or sulo-total operation, rocks the rod 146 clockwise. This movement of the rod 146 (Fig. 2) rocks the arm 228 clockwise, whereby through the link 227, the lever 226 is rocked clockwise and moves the link 225 to the left in the direction of its length. This movement of the link 225 through the engagement of its pins 231 with the plate 233 moves said plate to the left into a notch 245 in the gear 33, thus connecting said gear with the disk 235. At the same time the roller 236 is moved into a cam groove 246 in the disk 235. The movement of the link 225 also rocks the link 80 clockwise about the stud 78. As the disc 235 is connected to the gear 33,'the counter-clockwise movement of said gear and disk through the cam roll 236 moves the link 225 still farther to the left and rocks the link 80 still farther, so that when the lever 97 is lowered near the end. of the first half rotation of the gear 33 by the cam portion 95, as described in adding operations. the stud 99 moves idly in the elongated portion of the opening 100, thus preventing the link 80 from rocking the shaft 56 to return the various parts to normal position, thereby permitting the motor clutch to drive the gears and shaft 36 to a second rotation. Near the end of the complete rotation of the gear 33, the link 225 is moved to the position in which it was adjusted by the total lever 72 so that when the lever 97 is rocked clockwise a second. time by the second cam portion 95, the stud 99 engages a shoulder 248 in the opening 100 to lower the link 80 to rock the lever 77 and shaft 56 counter-clockwise slightly past normal position, but not as far past normal as in adding operations. Just before the second cycle of operation, the lever 48 (Fig. 7) is rocked to normal position to stop the motor, as in adding operations, by mechanism not shown here but fully illustrated and described in the Shipley application previously referred to. v

The care groove 246 (Fig. 2) in the disk 238 is timed to move the link 225 to the left between 221 to 301 degrees and then again to the right between 581 and 661 of the two cycle total-taking operation. The

arm 140 (Fig. 5) operates the arm 142 between 135 and 201 degrees and again be tween 495 and'561 degrees. As stated before the total lever does not move the plate 1.?4 to connect the drawer plunger lever 1.76 to the arm 142. The mechanical movement of the shaft 146 given to it by the movement of the link 225 is sufficient to effect this connec tion. This connection, as can be seen, is of fecte-d after the arm 140 has passed by the arm 142 in the first cycle of a two cycle operation, and is maintained until after the arm 140 has passed by the arm 142 in the second cycle of two cycle operation. It is thus seen, as mentioned before, that the arm 142 is moved idly in the first cycle of a totaltaking operation but is effective in the second cycle to operate the drawer plunger lever 176 and release the drawer. 1

Operatz'0n.-A brief description will now be given of an operation wherein a transaction includes a plurality of items. Let 1t be assumed that a cash transaction is made. The operator positions the total lever 72 in the adding position, as shown in Fig. 2, depresses amount keys 68 representing the value of the first item, the cash key which is one of the transaction keys 69, and then the starting key 71 which releases the mechanism allowing the machine to be operated either by the crank 30 or by the electric motor. This operation is repeated until all of the items have been registered, after which the total lever will be moved into a total or sub-total position, the starting key depressed, and the machine operated. During this total-taking operation, the cash drawer will be unlocked and moved forward into anaccessible position and an alarm bell sounded.
